To prevent-the material, from lodging* on 'and clogging the. screening fabric',' the screenin hopper should preferably be'jarred, and. 1t will be observed in the'4 construction ''described that rotation of the' ratchet member. 54 by sleeve 44 acts upon the lower nonfrotatable ratchet member 55', to

depress and thensuddenly release the latter, Y
